Hey guys. Lately, my RXV-800 has been shutting off when I turn the volume up past about -35. Now, it only does it when the Dolby processor is on and the center channel is active, and when I push the button for "effect off" and it's only in stereo, I can crank it up as loud as I want and it's fine. I've totally disconnected the center channel to see if there was some sort of short, but that didn't fix it. I really don't know enough about the construction of the receiver to diagnose anything, so if anybody has any ideas, please let me know. Thanks!
